Cook the rice noodles according to package directions. Drain and rinse briefly with cool water to prevent sticking and set aside.
In a small bowl, whisk together the tamari, lime juice, light coconut milk, maple syrup and Thai chili flakes. Set aside.
Heat a large nonstick skillet over medium-high heat. Add the pineapple and let it char for several minutes without moving too much until golden and caramelized. Remove and set aside.
Add the bell pepper and cabbage to the same skillet with a splash of water if needed. Cook for about 4–5 minutes until slightly tender but still vibrant.
Stir in the garlic and ginger and cook for about 30 seconds. Add splashes of water to prevent sticking.
Pour the sauce mixture into the skillet with the vegetables and let it warm through for about 1 minute.
Add the noodles and charred pineapple back to the skillet and toss everything together until evenly coated and heated through.
Top with the sliced green onions and fresh Thai basil leaves before serving.
